This image is of HMS Duke of Wellington a 131 gun sail & steam ship of the line launched in 1852.
She was originally to be named HMS Windsor Castle, but as she was launched on the day the Duke of Wellington died this plan was changed. She served as the flagship of the Baltic fleet during the Crimean War, but as her hull strength had been compromised by her conversion to steam during construction she was paid off in 1856.
From 1860 to 1863 she was guard ship at Devonport and then receiving ship at Portsmouth before replacing HMS Victory as flagship of the Port Admiral at Portsmouth in 1869. She was broken up in 1904.
